double ito::Shape::area ( ) const

return the area of this shape, or zero if the shape is a point, multi-point or line

QPointF ito::Shape::baseCenterPoint ( ) const

center point of this shape

QPolygonF ito::Shape::basePoints ( ) const

base points are various points that help to define the geometry in a precise description.

QPointF ito::Shape::centerPoint ( ) const

center point of this shape (after applying the transformation assigned to this shape)

bool ito::Shape::contains ( const QPointF & point ) const

returns true if shape contains the given point, or false if this is not the case. In case of shapes with an area of 0, this method always returns false.

< returns true if shape contains the given point, or false if this is not the case. In case of shapes with an area of 0, this method always returns false.

QVector< bool > ito::Shape::contains ( const QPolygonF & points ) const

repeatedly calls contains(point) for each point in points and returns a vector of boolean values to tell for each point if it is contained in the shape or not.

< repeatedly calls contains(point) for each point in points and returns a vector of boolean values to tell for each point if it is contained in the shape or not.

QPolygonF ito::Shape::contour	(	bool	applyTrafo = `true`,
		qreal	tol = `-1.0`
	)		const

returns the enclosing contour as polygon. If the shape is elliptic, an approximation is applied, where tol is the maximum distance between real contour and a line segment of the polygon (if -1.0, the tolerance is defined to be 1% of the smaller diameter of the ellise

void ito::Shape::rotateByCenterDeg ( double degree )

rotate this shape around its current center points by the given angle (in degree). This rotation changes the current transformation matrix, not the base points of the shape.

void ito::Shape::rotateByCenterRad ( double radians )

rotate this shape around its current center points by the given angle (in radians). This rotation changes the current transformation matrix, not the base points of the shape.

double ito::Shape::rotationAngleDeg ( ) const

return the current rotation angle (in degree, counterclockwise) of this shape (obtained by current transformation matrix)

double ito::Shape::rotationAngleRad ( ) const

return the current rotation angle (in radians, counterclockwise) of this shape (obtained by current transformation matrix)

void ito::Shape::setRotationAngleDeg ( double degree )

set the current rotation angle (in degree, counterclockwise) of this shape without changing the translation values

void ito::Shape::setRotationAngleRad ( double radians )

set the current rotation angle (in radians, counterclockwise) of this shape without changing the translation values

void ito::Shape::translate ( const QPointF & delta )

moves this shape by the given delta in the global coordinate system, which is the system where all base points are mapped using the current transformation matrix. This translation operation changes the current transformation matrix, not the base points of the shape.
